What is Slack?

Slack is the leading business messaging platform with 65M+ daily active users. It organizes conversations into channels, supports 2,600+ app integrations, and includes Huddles (audio/video calls), Workflow Builder, and AI-powered search. Acquired by Salesforce in 2021 for $27.7B, it remains the gold standard for team communication in tech companies, startups, and increasingly, enterprises.

Pros

  • Best-in-class UX for team messaging — channels, threads, reactions
  • 2,600+ integrations with virtually every SaaS tool
  • Huddles for quick audio/video calls without scheduling
  • Powerful search across all messages and files
  • Workflow Builder for automating routine tasks

Cons

  • Free plan now limits message history to 90 days
  • Can become noisy and distracting without discipline
  • $8.75-12.50/user/mo adds up fast for large teams
  • Video conferencing is decent but not as good as Zoom
  • Heavy resource usage — the Electron app consumes RAM

Frequently Asked Questions

Is Slack free plan enough for small teams?
Slack free plan gives you 90 days of message history, 10 app integrations, and 1:1 Huddles. For teams under 10 who do not need message archives, it works well. The main pain point is losing older messages after 90 days.
Slack vs Microsoft Teams: which is better?
Slack is better for developer teams, startups, and companies using diverse SaaS tools. Teams is better for enterprises already using Microsoft 365, as it is included free. Slack has a more polished UX; Teams has better video conferencing.
Does Slack own my data?
No. Slack states that customers own their data. On Enterprise Grid, you get data residency controls, HIPAA compliance, and custom retention policies.

Editor's Take

Slack changed how teams communicate, and nine years later, it is still the best at what it does. The channel-based messaging just works — threads keep things organized, reactions reduce noise, and Huddles replaced 80% of my scheduled meetings. My honest complaint is the free plan gutting message history to 90 days. For a tool that becomes your team's knowledge base, losing old messages hurts. If you can afford $8.75/user/mo, Pro is absolutely worth it. If you are a Microsoft shop, Teams is fine and free with your M365 license. Everyone else? Slack is still the answer.
